RC India

As the topic name says it. Need it, could be a 8000mAh LiPo too . Will buy if competitively priced :)

Has to be 3S 11.1v btw...

no one upto the challenge ? :giggle:

Challenge?
What's the challenge?  :headscratch:

finding a LiPo at a competitive price :P

bought a 5000mAh Zippy for 2700 earlier. Need something around that price point.

Recently bought HAIYIN 3 cell 5000 mah 35 c for  :Rs:3200 + 80 shipping...

couldn't find a better deal for reputed batteries.... :banghead:


Just  hope that batteries delivers what they call it for..... 8-)

saw 4000 mAh for 1800 ... that seems good :)

and those multi one cost almost 3800 XD nope not cheap ( still very light though )

1800.. ??? ??? for new one?  if yes from where? (:|~ (:|~

DONT BUY AL !!! I too need a few for myself :D

hahaha don't worry ill buy only one.. :thumbsup:

I WISH I wish someone could sell the Multistar one for 3k , will buy it in a snap :D

never tried multistar but heard giving decent flight time...
my turnigy 2200mAh gives only 2 mints.

2 mins !!?? whats the weight of your quad ??

My wolfpack gave around 5-6 mins (2200mAh)
and the 5000mAh Zippy gives about 14-15 mins

it weight around 1.1kg with battery..  using turnigy multistar 2212 920kv motors

mine weighs 1.5 with 5000mAh lipo and have 2836 1100kv motors....

i also have wolfpack 2200mAh. while using woflpack my quad start giving battery warning in 30-45 sec of flight ... don't know why?...  

well yea my wolfpack went kaput not, in LiPo mode the charger doesnt charge, ( says cell voltage too low ) , take it to NiMH and says voltage too high, basically its gone, i just use it for my basic testing purpose now ...

tomorrow i going to try both batteries in parallel and lets see what happens...  i think in parallel 4400mAh they will give almost 5-6 mints... maybe ..

with almost double the weight :P

hmmm with both the batteries it will weight around 1.5 kg...

that the normal weight of my quad XD ( with 5k lipo )

i don't know why this happens as i watch many reviews on youtube etc. people said there 2200mAh battery is giving 7 mints of flight time... and 4000mAh giving 11-12 mints...

battery is not holding enough charge on it

but turnigy2200mAh battery is new.. only 4 cycle charged..

discharge rate???

somethings wrong bro ... 2200 with 1.5kg weight gives me approx 6 mins
5000 gives around 15

I don't think there is anything wrong, it must just be that your motors draw less current and are more efficient.. My WolfPack 2200mAh gave me around 4 minutes with a 1.2 kg quad (approx. including battery). However, it could not handle the discharge and is now just lying there damaged. My Wild Scorpion 3500 mAh gives around 7 minutes following the 80% rule.

ok... well i too didnt do any rigorous flying, basic hovering and and stuff...

whats the 80% rule ???

The 80% rule says that you should not have to put back more than 80% of the battery's capacity while charging. Your IMAX B6 will tell you how many mAh it put into the battery after charging. Thus, for a 2200 mAh LiPo, this should not be more than 80% of 2200= 1760 mAh. This gives the most cycles from the battery. This translates to around 3.7V per cell minimum for me.

the 80% rule is you dont use all your 2200mah, you use max 80% for lipo safety!!
and i know a guy offering 8000mah battery for 3000rs, but the battery is 70 flights old, acttually it is 2x4000mah!!and the brand is haiyin!!

JK

ok .. but i need flight time so i charge it to a full 100 :(

also, 70 flights is really old :(

You can charge it to 100% but not discharge it full!!

And ya 70 is a big number for a lips!!

Regards,
JK

 idont discharge it full ... have an alarm , the moment the quad cant lift at full throttle too , i take it out and recharge it.

wolfpack discharge rate.. 25C  turnigy discharge rate 20-30C

What voltage reading do you get at that stage?
I hope you keep the LiPo alarm connected while flying your model.

yes, i set the alarm at the lipo alarm itself, ive kept it at 3.10

3.10v is too low. Not recommended. Will reduce your battery life.
Better keep it at 3.7v or 3.8v or else at times you might not get enough time to safely land your quad.

BTW, at what voltage usually your quad can't leave ground?
Usually a properly designed quad can leave ground even at 3 volts.
If your quad is not able to leave ground even at 3.1+ volts then either it's too heavy or something's wrong with the setup (Motor/Prop combo)

If you are looking for higher flight time then stick to MultiStars since they provide the best storage (mah) to weight ratio which will also be beneficial if your quad is already too heavy.
Just make sure that the MultiStar that you're choosing should be able to deliver the required amps.

today i full charge wolfpack (2200mAh) and fly.. my naza start giving low battery indication after 40-50sec.. i fly my quad till battery doesn't lift it any more.. and gives me around 5-6 mints of flight time...  
confused y naza start giving me led warning in first mint...

but while using turnigy (2200mAh) it works fine

@gunnu, please post the voltage reading of both batteries at fully charged state.
Sounds like your Wolfpack LiPo have got damaged due to Low Voltage at some point of time due to which LiPo's usually won't get fully charged and will also show great deal of voltage sagging under load, hence the quicker low battery indication while flying.

wolfpack voltage. 3S-12.5
S1- 4.13
S2- 4.21
S3- 4.23

turnigy 3S-12.5
S1- 4.17
S2- 4.17
S3- 4.19


charger imax B3 pro

Are these figures from the batteries in fully charged state?

yes..

That is because the WolfPack LiPos are not of such good quality IMO. The voltage sags a lot under load. Even my LiPo alarm used to beep when I left it plugged in while flying. The LiPo finally died. See this thread: http://www.rcindia.org/batteries-and-chargers/wolfpack-2200-mah-25c-problem/ (http://www.rcindia.org/batteries-and-chargers/wolfpack-2200-mah-25c-problem/)

today i gives me flight time for about 5-6 times (first time this much flight time) but led warning in 40-50sec.. forgot to attach lipo alarm..

Hmm, then i have bad news for you.
Both of your LiPo Packs have already got slightly damaged which can be due to any of the following 2 reasons:
1) Keeping LiPo's at fully charged state for prolonged time. Like weeks or months. You should always store LiPo's at storage voltage of 3.7-3.8 volts per cell.
2) (The more likely reason) You have allowed the batteries to get discharged too much. Usually letting voltage on any cell of a LiPo pack go below 3.8 volts is simply calling for trouble.

The more you do any of the above, the more the cells will get damaged and they will show following abnormalities:
1) They won't get fully charged (i.e won't reach 4.23 volts per cell) = Won't store full 2200mah charge.
2) They will show a great deal of voltage sagging under load = When you'll fly your model and give mid to high throttle, the voltage will drop down to 3.9, 3.8 volts, etc or even lower due to increased internal resistance making the LiPo usable only for a very short amount of time till it reaches the dead low.

Cell1 of your Wolfpack seems most degraded since it has the least voltage at fully charged state out of the 6 cells, hence the early LED Warning.
The Turnigy one seems to be comparatively better but still it's still not in the perfect condition.

Always fly with the LiPo Alarm.
And always keep LiPo Alarm configured at 3.8 volts and you will be able to use LiPo's for a long long time.

Usually the more time you let pass after a LiPo hit low voltage (2.5v or less for any cell) the more it gets damaged and it's internal resistance increases more and more.
Go even lower and the cell will start puffing due to gases releases within the cells due to a certain chemical reaction.
Eureka, you just invented a LiPo powered Paperweight ;D

While your LiPo's (Specially Turnigy) is still usable, you are not able to get it's full advantage while in flight.
Continue with it or get a new one, your choice. But never fly without the LiPo Alarm. :thumbsup:

thanx sir.. from next time ill keep this parameters in mind...

thanx..
regards

@IHS: well it still takes off at 3.3 easily. i wrote wrong i guess, ive set the alarm at 3.7 at that point i know that i have some time before the quad hovers at full throttle ..

and yes i have my eyes on the MS LiPo , only if the price drops a bit :(

if you still looking for battery then i can arrange

ZIPPY Flightmax 8000mAh 3S1P 30C >> Rs. 3900
Turnigy 5000mAh 3S 20C Lipo Pack  >>Rs. 2400
ZIPPY Flightmax 5000mAh 3S1P 40C >> Rs. 3200

Freight: Rs. 200 (shipping within India)

Delivery period max 10days (just to be on a safer side)

Need 2. PM

WOW !!!!!!!! That is some thing that can be called COMPETITIVE  :)

@ Jayesh jain sir, Can I expect to see this batteries in your store for the same price ? If yes , I can assure you are going to rule the LHSs in India :)
Looking forward to buy a 5000 mAh. Heck, I just spend out all the bucks I had on  some motors and Servos :banghead: . Can I hope this prices will be as is for a month or so ?

Still I can't believe it, SIR, Was that a Typo - I expect not with all my will !!

yes ! Contacted him :) Finally the prices I was looking for ! :D

Ive contacted him , if things go well, you dont know how well and long a good word for a LHS can go here :)

that is one hell cheap!! and best of luck with the store!!

regards,
JK

Good deal..

Next time i will buy from you, not from hobby king.

Thanks

Suraj SIR ji, that was definitely was not a typo. But these are only offer price for RCindia community. And I don't for how long they gonna last. It all depends on response we get from you people.

We have a strong foothold in robotics community. We are just trying to enter RC market and trying to understand it.

PS: You guys might know Ankur Kaul (allthatido). He personally know me and he was my roommate. From him I got inspired into RC. We help each other in some or the other projects. His website is also hosted on my server. (whitespark.in, jnet.in) Another sales pitch  ;D

Looking forward to buy a Turnigy 5000mAh or Zippy flightmax 5000mAh soon . Would like to know the weight of these batteries.
Will you be stocking those Multistar batteries ?

ill go for flightmax 8000mAh....

ZIPPY Flightmax 5000mAh 3S1P 20C weight is  404g (including wire, plug & shrink wrap)

Currently there is no plan to sell multistar batteries.

Can you do a zippy compact 5s 5000 mah , if so what would be the price ?

I have 3 NIB 5000mAh 60C-1255C hard case packs for sale:
